I think after much research and really get feeling I am going to ask Dr if I can do the school that attaches at spine instead of pstim that attached to ear. I have only found one glowing review and it really bothers me that it makes my so called alarm I head that says " hey that hurts don't do it" I like that sense I don't want to don't that out and don't believe there is enough long term effects at this point. Will keep writing and please keep me in loop with personal information that might help. Thanks to you I feel better about the whole idea.
